Sickness

Everyone has their own sickness,
But what do I do,
Who is there to turn to?
If I barely trust myself,
How can I rely on someone else?
So many questions left unanswered
My disease is as deadly as cancer
And since I see no cure,
Why suffer with this pain I endure?
It would be easiest to end it all,
But what if there's someone to catch me when I fall?
